[Springframework-developer] Question about need for DAo's or Business Objects to keep a session factory refrence

[Cameron B. <ca...@da...>]

I am just beginning to use the Spring framework, and so far I am very 
impressed.

One thing that I don't quite understand is the mandatory requirement for 
each DAO and BO (Business Object) to support the set/getSessionFactory 
method.

The reason that I say it is mandatory is because the only way to obtain 
the current session (as far as I know) is to use 
SessionFactoryUtils.getSession(SessionFactory...).  This means that each 
DAO/BO requires a setSessionFactory property to be able to be passed it 
from the spring container.  This also requires that each DAO/BO to be 
configured to bind the SessionFactory instance within the 
applicationContext.xml

What I would think would be a simple and quite common use case would be 
for an app to require only one session factory. Therefore I think that 
the SessionFactoryUtils, and related classes , could use a static field 
to store the 'default' session factory.

Has something like this been considered ?
Do you think that this is a good or a bad idea ?

Cheers,

Cameron.
